MGR/Billy's review"Behringer BX4500H"

Behringer Ultrabass BX4500H
This is the Ultrabass BX4500H bass head by Behringer. Price point you are probably thinking 'Wow this is great' In this case 'Buy nice or buy twice' rings true.

I must say Behringer has an excellent customer service department, but I would suggest saving a little extra to buy a better amp.

My predicament was, let a nice bass amp sit in my car for 8 hours in the city while I work and lug it up and down steps by chance it doesn't get stolen from my car or buy a cheaper rig and leave it at my practice space.

That is why I ordered the Behringer. $250.

It offers you plenty of options in the preamp. The knobs are: Gain, Ultra Bass, Bass, Mid, Treble, Contour, Shape, Output and the front mounted DI out.

The sound was never call your friends over good, but I was able to cut over a 4-piece rock group.

The clip meter on the front is just about useless. Mine never really worked right, but hey who cares.

Within 90 days of owning the thing it overheated just from normal use. I wasn't really maxing it either. I ran the gain at 3 o'clock hoping to get a little grit and then my output was around 10 o'clock.

It was mounted in a carpeted box. Weight was reasonable.

Every company lets a few duds out of the factory and maybe that was what mine was. I called customer support when mine over heated and they set me up with a new amp in a timely fashion.

MGR/PeteBassclef's review"Behringer BX4500H"

Behringer Ultrabass BX4500H
Bass player since 1966.(15 yrs old!)
Played all sorts of styles since then.
60's pop,70's rock,80's glam.

Weeks of internet/forum research.Decided to ignore "snobs" comments about Ashdown copy
& bought the Head, 1x15 Cab & 2x10 Cab for under £500 incl delivery.Gear arrived in 3 days.You simply can't beat that for a full stack.
Bought via the Internet from GAK (UK)

Price! Price! Price!
The gear also looks good.It does look similar to Ashdown,what's wrong with that?
I got the full stack for the price of an Ashdown head.
Plenty of power,& once you get used to the EQ section,loads of tonal variations via the SHAPE control.The cabs don't break your back either.

The Ultrabass function doesn't impress me, so I never use it.I wish Behringer would replace this with Compression control.
I rated this amp 4 out of 5 because it didn't have Compression control.
Regarding the don't have any control over the Tweeters.They are either On or Off (via a switch)
Too drastic sometimes, so a pot would be better.
Master volume pot is way too sensitive.
Would prefer it to be "notched" like Trace Elliot amp.Sometimes you need a quick tweak so you have to be careful with this pot.

Top marks for construction & quality.
1 year using it. No complaints here.

Apart from no compression control & the sensitive master volume, I can't fault this gear considering the price.

MGR/Guido's review"Behringer BX4500H"

Behringer Ultrabass BX4500H
Bass player for 32 years. Playing locally though I've been in a couple of signed bands and toured the U.S. Pop alternative is what I'm listening to primarily now.

Bought the BX4500H at Guitar Center for $250 on credit card. I was in search of the ever elusive, "Magic Tone"

Can't beat the price or the tone, now that Behringer solved the noise problems on these units. I tried a couple units on opposite ends of town and, NOISE. Got a much newer unit and, perfect!!

Right now I can't think of a single thing I don't like about this unit. I've only had the unit for about 2 hours. I plan to use it tonight on a gig.

Totally compact and solid.

I don't know how Behringer does it with their products for the price. I've owned several Ampegs, SWR, Acoustic, Marshall, currently own a Gallien-Krueger. This thing sounds like an Ashdown bass head but for 1/4 of the price!! For me, Behringer hit this one out of the park!!

Good morning.
everyone has already said précédamment forestay.

in 5 rows because all has already said précédamment forestay.

If your budget is not too high and the bass player you are (beginner or average), then the purchase you will not be disappointed as long as you have speakers that go with my head since 2006 this is me believe it was seen, hey nothing moves ever crashed always the same power of sound.
I understand not to say that this shit an amp, for me it was they who shit in your ears.

SlapKid's review (This content has been automatically translated from French)

Behringer Ultrabass BX4500H
I had this thing 6 months, it's downright wrong level and its power.
Supposedly 450w, you laugh, on the same tower (hugheskettner115 410) a 200 watt Fender KXR sounded louder and mostly clear and distinct.
Octaver embedded nice, and the amp can run on 2ohm without damage (according to product manager germany in 2005).
Equalizer draft, still better than nothing, although I have not tested external preamp straight into the back loop.
No noise when you play it, it's something.


It's simple, and it never gets a good sound!
I totally thought my tour was lame ...
On a small 12-inch largebande to play softly with the octave was almost acceptable ...


It is confusing, as coming from the depths of the cellar, zero dynamics, definition absent, difficult to hear what we do really with this amp.
In addition, it sounds so Raplapla that mounts the volume in the hope that something happens and then what happens is ... a limiter that sets off alone. Which suits the situation of course! Like what it could sound even less ...

I regret not being able to try a SansAmp bass right in the return loop, which would have allowed us to identify the culprit (preamp or amp total).
I have the distinct impression that nothing would do, hopeless cases.


Terrible! Complete lie, too expensive for the crap that is (still reliable after various forums), especially not only buy this amp.
I think a SansAmp amp plus a sound system (it can be found for less beefy 200euros) is a better investment, for a price and an equal weight.
The only consolation, through the din of its product descriptions Bebert I easily sold my amp. PHEW!
Marshall MB30 has a sound quality that will never Bébert. And you can even a driver amplifier with sound, by the way! That's my advice for cheap, and left the tower and the amp sound to local while MB30 made the round trip with the bass at home, versatile and always better than Bebert. Porcaro from Toto made this plan with a SansAmp elsewhere, and I never found it lacking in its ...

Behringer Ultrabass BX4500H
-Transistor amplifier
- 450Watt
- Entr jack, headphone output, DI output on the front, Speaker Output jack or two in output neutrik.
-EQ option is 5Bande with its bright deep or more processor Ultrabass and Shape any two can operate at the same filled him or footswitch.


Configuration and could not be more simple and sound s'obtien With easy, using an equalizer and more redo my boss I could not sound more than half an hour.
The manual is clear but the French version is less than aproffondie the English or German. But with some basic English you soon realize all the posibilit of the amp.


It is suitable for all styles and all the bass. Since this is not the high end Specializes it too so that the amp has all the purses of all styles to use. Played in the equalization push to 3 / 4 in the bass and treble dan decrease by adding the option shape is obtained and the deep blues sound trs, trs round and heavy, by making the cons Conversely it is well funky raproche of the Kool and the Gang.


I use it for a year in both reiterated that concert and at home. I aessay many MODEL sometimes very expensive but plsu cete head amp make a report has been unbeatable quality, I recommend ialleur of a bass player all the less fortunate to buy this head amp waiting to s'acherter a Mesa Boogie or Ampeg

Behringer Ultrabass BX4500H
-Amp Transistors

-450W @ 4ohms

-Between Active / Passive, Pedal to the Inrush Ultrabass and Shape, XLR / Jack, Send (or Tunner) / Return

-Gain Equalizer 5 bands, Ultrabass and Shape Effects, Limiter, Output, and Functions Dee Bright

On paper everything looks great but ...


Setup is extremely simple, we get the sound you quickly DSIR trs (If you are not too demanding)! court, but the manual is simple


The price is good for drinking. It is extremely versatile, from jazz to rock, to groove mtal, anything can happen. By careful against your bass, if it is a low-end bass, the sound will come out will not potable.
The 450W on paper never go out, the sound is a bit low for a 450W and pushes high volume of grsillements appear endless.

The fan is loud enough and it drengeant. The overall sound is trs blah indeed missing potato, a large volume grsille for résumé sound is simply ugly.


For a budget may be suitable for some time. But if you are trs demanding your sound, go your way the head is not worth the trouble.
Actually since I tried the head Markbasse LMII I fell in love and my head is that Behringer me trs little (and right now at all).
For the report quality price goes, there's the same when at the end.

With exprience, I think I'd wait a while to SAVE not to pass on this Behringer head.

For bassists express go your way but for beginners, a little pass (and yet) !!!!!!

XplODeR's review (This content has been automatically translated from French)

Behringer Ultrabass BX4500H
So it's a transistor amp with a 450W 4ohms provided
There is an active input and a passive input (Jack of course), and multiple outputs
<ul> XLR / Jack Tuner Output for baffleUne Jackunas Out Back Jack who is also </ul>
A pedal to trigger the ultrabass and shape is provided.
As the setting there is the gain, the bass, treble and midrange équialiseur a short and the volume of course.
Effects as there is Ultrabass and Shape, Bright and Deep


Personally I found the simple setup I quickly find the sound I wanted. The manual I can tell you if it's clear I have not read: p


Pop-Punk/Punk-Rock I play and I have a 4x10 cabinet behringer from home and I had a sound that was well suited to my style of music.
I play a Yamaha RBX270 and void.


I use it for just over two months and I do not regret my purchase I had bought it for lack of resources but I have no regrets and I do not separate from me so soon. I had the opportunity to try on at a friend's 300W and it's true it's a long way.

This is a good quality / price ratio.

With the experience I do not see why I do not repeat them

tontonseb's review (This content has been automatically translated from French)

Behringer Ultrabass BX4500H
All t adj said the head is given to 450W. You can connect a speaker to Speakon jacks or 2 on.


I have seen dj simple at the dashboard. We must fiddle 5 minutes to get his sound.


Let's be clear: the function is not ultrabass intrt for me unless I put the dub. The function shape me parat complicated to use. As against the bright feature gives me satisfaction: it allows DGIG a warm and a little fat, typ "lamps". This is the one that suits me.


I tested this amp from a vendor and a friend's house, which can be a good idea. I jou it with my bass: Squier a PB. The head connects to a silent home aluminum baffle 4x10 Behringer precisely.

I prcise that the baffle is furiously thinking a Behringer Hartke, in terms of look like her: a slap in the mdiums. I think a more appropriate one lover funky slap that a fan of Motorhead and punk-rock like me. I'll have to retry with a 15-inch to bring out the bass and the "fat" of the amp.

The head is reminiscent of an Ashdown amp: same knobs and a VU prsence nitre (dcoratif more useful). But the sound is not as vintage less bright trigger function. Apart from that the sound is plutt think the Hartke or Peavey: own (I got too), with a slam in the CT mdiums (4x10 aluminum but has a lot to ).

A salesman assured me that the firm had Behringer amlior its reliability and its lookout bass amp going to the BX300 BX450. I knew the brand for its dj microphones, mixers and PA speakers, and it's "good not too expensive." For that we go head to carrment trs cheap: 350 euro and 100 Toulouse under parat it in Germany.

For me it is clear: one or two tests with a 15-inch cabinet or a 2x10 "box" instead of aluminum. Function bright background. And if a glue always have a good big sound fawn vintage Ampeg, Mesa Boogie and Ashdown that price, I take the plunge.

-Very easy to use, fairly basic settings

-It is quite easy to get a good sound

-The manual is very small, it explains each button / connections but no further.


He gives a very good sound.

I use it with a low bad enough without purpose and it gives a good well rounded.

-With the settings for a bold and well, it's been really fat ...

-The effect Ultrabass it's funny but horrible so I do not use it.


-I use it for one month and no problems.

-The better the price, the less is the weight with the enclosure when to climb stairs.

-No, I have chosen over the price because I am limited financially and I did not expect to have a good sound the same.

-Value / price to be seen how long it will take but I think the good quality despite the price.

I probably do it again-this choice.
